CHARLES D. ULMER, OF BOSTON, MASSACHUSETTS. Letters Patent No. 86,955, dated February 16, 1869.

IIVIPRQ'VEMENT IN' ,ATTACHING- HEELS TO BOOTS.

To all to whom these presents shall come Beit known that 1, CHARLES D. ULMER, of Boston, in the county of Suii'olk, and Commonwealth of Massachusetts, have made an invention of a new and useful Mode of Attaching Heels to Boots and Shoes; and do hereby declare the following to be a full, clear, and exact description thereof, due reference being had to the accompanying drawings, making part of this specification, and in which- Figure 1l is a section of a boot containing my invention or improvement;

Figure 2, a top view cf its detachable heel, as removed from the boot;

Figure 3, a section of the heel and sole of a boot, showing the application of my invention;

Figure latch applied to the heel', as hereinafter explained; while Figure 5 is an edge view of the metallictongued plate applied to the sole in manner to be explained.

The invention comprising the subjectmatter of this patent has reference to a mode of manufacture of boots and shoes nowbecoming very general,whereby the heels of such boots and shoes may be removed from and applied tothe sole thereof at pleasure, one object of suchv application of the heelsbeing to allow of an interchange between the heels of a pair of boots, according to varyingconditions of the wearupon them; another object of such dispositionlof the heels being to .enable worn-I out heels to be replaced by new ones.

My present inventionhas reference to means foraccomplishing this changeable union of the sole and heel of a boot or shoe, in a simple, economical, and durable manner, and consists in applying, to the lower surface of the sole, a metallic plate, provided with a tongue in rear and a bent vlip in front, the purpose of the tongue being to extend into a latch or socket applied to the upper surface of the heel of the boot, and by this means confine the heel to the sole, against lateral oroblique thrusts,while the lip, being secured tothe front ofthe heel, insures the proper position of such heel, with frespect to the soleand slipping of it upon the sole.

In the drawings before mentioned as accompanying this specification, and which illustrate my invention- A. represents a boot, of which a is the upper,..b, the sole, and c, the heel.V

4 is an edge view of thetransverse plate or socket, 'against any longitudinal v In carrying out my invention, I form the heel, shown at c in the drawings, independent of the sole, and made of wood, or any other desirable material, and I apply securely to the upper surface of the' heel, and in rear of its centre, a transverse metallic strap or bar,-e, so

formed or provided and applied to the heel as to produce a socket or latch, f. l

lo the under side of the vsole of the boot, and at its rear end, I drmly ix a broad metallic plate, g, such plate corresponding.y inl formto and being slightly less in size than the heel, in order that the latter shall entirely obscure it from sight. i

v'lhe'plate y is formed with an offsetting tongue, h., punched from it, and depending below it, as shown in fig. 1 of the accompanying drawings, the purpose of this'tongue, as before premised, being to extend into the socket f, where the heel is applied to the sole, and

4forced forward to its farthest extent, thus securely holdl ing the heel in place.

To insure the union of the heel and sole, as thus created, against lany longitudinal pressure upon the former, I form the plate g with a .hanging lip, ,-to extend in front of theheel, and to which it is secured by a screw, or other suitable means.

From the above descriptionof the purpose of ,my

i invention, and the mode of carrying it into eect, the intelligent reader will at once perceive lthat the heel may be readily detached from. the boot, by removing the screw which confines it to the lip fi, last explained.

' Claim. v I claim as my invention, and desire to secure by Letters Patent of the United States- The device hereinbefore described for applyingjthe vheel ofa boot or shoe to its sole, the same consisting ofthe transverse latch or socket f and the plate g, the former being fixed to the heel, while the latter is axed to the sole, and provided with the tongue h, and secured Vto the heel, when Asuch heel is in wearing position upon the sole, as shown, the Whole being constructed, and. ar-L ranged, and operating as before described.

v CHARLES D. ULMER.
